DataLab Web Roadmap

This page summarizes the development roadmap for DataLab Web.

Completed ✅

Core Features

  • Extrapolation (power-law, Richardson, Shanks, Levin u-transform, custom formula)
  • Error propagation (numerical derivatives, uncertainty synthesis, constants support)
  • Fitting (polynomial, inverse-power, Padé, power-limit, custom models)
  • Statistics (mean, sample variance, weighted variance)
  • LaTeX table generation and optional PDF compilation
  • CSV export
  • Dark/light theme support

UI/UX

  • Unified “?” help buttons
  • Keep implementation details out of the main UI (technical info stays in docs)
  • Responsive layout for mobile
  • Theme toggle

Security & Deployment

  • CSRF protection
  • Input validation and size limits
  • Sandboxed LaTeX compilation
  • Secret key configured via environment variables
  • Deployment documentation (Gunicorn / Nginx)

Short-Term (implemented) 🚀

1) Built-in docs pages

  • Flask routes: /docs and /docs/<page>
  • Markdown rendering with HTML escaping
  • Whitelist mapping to prevent path traversal
  • docs.html template and navigation entry

Mid-Term (implemented) 🌐

2) Internationalization (ZH/EN)

  • Frontend i18n module (static/js/i18n.js)
  • Bilingual UI strings and a language switcher
  • Remember language preference in the browser

3) Interactive help system

  • Help specs stored in shared/help_specs.json
  • Method help and formula function list (ZH/EN)
  • “?” modal UI; help content follows language changes

Future Ideas (planned)

User Experience

  • Interactive onboarding/tutorial
  • Built-in example datasets
  • Local computation history

Features

  • Batch processing (multi-file input)
  • Parameter sweeps
  • More extrapolation methods and fitting models

Performance

  • Result caching
  • Async job queue for heavy computations

Internationalization

  • Expand bilingual docs coverage
  • Additional languages

Principles

  1. Security first: validate all user input; sandbox LaTeX compilation
  2. Backward compatibility: new features must not break existing workflows
  3. No tech stack in main UI: technical details belong in /docs
  4. Single source of truth: specs/docs/help stay consistent
  5. Progressive enhancement: core features work without JS; JS adds convenience

Contributing
